Adjusting the carburetor (idle)

makesadjustmentoftheidleandmainnozzlesuperuous,and
these are impossible on this model.
If necessary, the idle speed can be adjusted with the adjusment
screw (8).
Idle speed correction is necessary if the blade moves in
idle (i.e. when the throttle is not actuated).
The blade must be completely stationary in idle!
Use a screwdriver (7, blade width 4 mm, part no. 944 340 001)
for this adjustment.
Let the engine warm up for 3-5 minutes before adjusting the
carburetor.
Avoid high engine speeds!
Adjusting the idle speed
Turning the adjustment screw (8) counter-clockwise:
Idle speed goes down.
Turnign the adjustment screw clockwise:
Idle speed goes up.
Caution: If the blade still does not come to a stop in idle
even after idle speed adjustment, do not work with the
trimmer under any circumstances. Take it to a DOLMAR
service centre!
